SAN JOSE, CA \u2013 March 4, 2025 – Phison Electronics<\/a> (8299TT), a leading innovator in NAND controllers and storage solutions, announced today that its PCIe Gen4x4 PS5022 controller, designed for automotive applications, has become the world’s first SSD controller to receive ISO 26262 ASIL-B compliance certification. This automotive certification highlights Phison\u2019s adherence to the functional safety (FuSa) standard in the NAND industry, underscoring Phison\u2019s commitment and technological leadership in the automotive storage<\/a> market.<\/p>\n The ISO 26262 ASIL-B compliance automotive certification is a critical standard for the functional safety of automotive electronic systems, ensuring that electronic components within a vehicle can detect random failures in real time and can transition into a safe state to support impact prevention for driving safety. As Advanced Driver Assistance Systems (ADAS) and autonomous driving technologies advance, the demand for secure storage systems in vehicles continues to rise. Phison’s PS5022 controller has passed this certification, covering multiple aspects of hardware and software design. Phison has also dedicated significant resources to Part 6 (firmware validation) to enhance firmware security and reliability<\/a>. With automakers increasingly requiring this certification for automotive storage devices, the successful certification of PS5022 further strengthens Phison\u2019s leadership in the automotive storage sector.<\/p>\n This ISO 26262 ASIL-B compliance is an advanced stage compared to the ISO 26262 ASIL-B Ready, which indicates that the product analysis meets certain safety requirements under Part 5 but does not fulfill the complete design and verification requirements of ISO 26262 and necessitates customers to conduct their own comprehensive safety assessments and validations. In contrast, ISO 26262 ASIL-B compliance ensures that the product has undergone a complete analysis, design, and validation process for automotive functional safety, enabling real-time detection and mitigation of potential risks caused by random failures, thus providing a higher level of safety assurance for the automotive storage market. Phison\u2019s PS5022 controller obtaining ISO 26262 ASIL-B compliance certification signifies that the product has successfully passed the full certification process under ISO 26262 ASIL-B. This means that every stage\u2014from design and development to validation and application\u2014meets functional safety standards solidifying Phison\u2019s position as a preferred choice in the automotive storage market<\/a>.<\/p>\n With over 15 years of expertise in automotive storage controllers, Phison has consistently provided high-performance NAND controllers for major global NAND manufacturers. Of note, Phison\u2019s ASIL-B certified PCIe Gen4x4 PS5022 controller is featured in Micron\u2019s 4150AT SSD<\/a>, which is the world’s first automotive SSD featuring quad-port and SR-IOV functionality. This product serves as a crucial foundation for next-generation automotive architectures<\/a>, delivering enhanced efficiency and safety for intelligent driving.<\/p>\n \u201cPhison\u2019s achievement of the world’s first ISO 26262 ASIL-B compliance certification for an SSD controller is a testament to Phison\u2019s technological expertise<\/a> in NAND controller design, and sets a new benchmark for the automotive storage market,\u201d said Michael Basca, Micron vice president of embedded products and systems. \u201cEnsuring functional safety is critical for us when architecting automotive solutions. As an instrumental piece of our automotive 4150AT SSD, Phison\u2019s newly certified controller further enhances the performance, reliability and stability of our solution. We look forward to continuing our collaboration with Phison to drive advancements in intelligent automotive technology and provide safer, more efficient storage solutions for future vehicles.\u201d<\/p>\n \u201cAchieving ISO 26262 ASIL-B compliance certification required a tremendous investment from Phison, spanning four years, engaging over 300 engineers, and costing tens of millions of NTD. This effort has resulted in the world\u2019s first SSD controller to meet this automotive standard\u2014PS5022,\u201d said K.S. Pua, CEO of Phison Electronics. \u201cThis accomplishment reflects Phison\u2019s commitment to quality and innovation and reinforces our long-term dedication to the global automotive market. We are especially proud that this newly certified controller is featured in Micron\u2019s advanced automotive SSD, the 4150AT, the world\u2019s only quad-port SSD. Moving forward, we will continue to deepen our collaboration and drive the advancement of automotive storage technologies.\u201d<\/p>\n Phison Electronics Corp.
